Rock Crab - Good/Bad?

[Beverly]

Hey, Quinn, how many of my crabs do you have? I've only rocked one. It was a disgusting thing to do, but that week, I had no alternatives. I know three of my crabs fed triggers at AI. Can't remember if anyone else picked up crabs from me besides you, but I sure found a lot of freaking crabs in my tanks

I also have two captive bred seahorse tanks where crabs of any kind are just asking for dead seahorses. Not my idea of fun
